Concept note-1: -On December 7, 1941, Japan staged a surprise attack on Pearl Harbor, decimating the US Pacific Fleet. When Germany and Italy declared war on the United States days later, America found itself in a global war.
Concept note-2: -On December 7, 1941, the Japanese military launched a surprise attack on the United States Naval Base at Pearl Harbor, Hawaii.
Concept note-3: -Because American military leaders were not expecting an attack so close to home, the naval facilities at Pearl Harbor were relatively undefended. Almost the entire Pacific Fleet was moored around Ford Island in the harbor, and hundreds of airplanes were squeezed onto adjacent airfields.
Concept note-4: -Japan’s military thwarted a declaration of war on the United States before Pearl Harbor said former Japanese Ambassador Takeo Iguchi at a talk sponsored by the Center for National Security Law Sept.
Concept note-5: -War with Japan appeared imminent, and on Dec. 1, the Japanese navy suddenly changed the radio call signs of its ships. This shift was ominous because the Communications Intelligence Unit at Pearl Harbor plotted the position of the Japanese fleet by intercepting these signals.
